AB Design

used in single-case evaluation. A-baseline phase and B-intervention phase

ABAB withdrawal/reversal design

used in single-case evaluation. if intervention was cause of improvement then in the second baseline phase target problem will be similar to original baseline. When intervention is reintroduced target problem should improve again

baseline

phase in single-case evaluation. repeated measure of a target problem before new intervention or policy is introduced

generalization of effects

occurs when intervention affects behaviors in addition to the target behavior

multi-baseline design

a type of single-case veal.- attempts to control for variables by having multiple baseline and intervention phases

operational definition

concrete and specific definition of something in terms of operations- can be observed and categorized

reactivity

a process in which change in a dependent variable in induced by the research procedures

replication

repeating study to reduce error. duplication of withdrawal or reintroduction of an intervention to hep increase internal validity

self-reports scale

subjects all respond to the some list of written questions. specifically designed to measure a particular construct

single-case evaluation

time-series design used to evaluate the impact of an intervention or policy change on individual cases

triangulation

the use of more than one imperfect data-collection alternative in which each option is vulnerable to different potential sources of error
